The Challenge
Critical Challenges in Maritime Engineering
The marine industry faces a unique triad of manufacturing hurdles that traditional processes cannot efficiently solve.
01
Extreme Corrosion
Components must withstand constant exposure to saltwater, humidity, and high pressure. Standard alloys corrode rapidly, leading to frequent replacements and safety risks.
02
Logistical Nightmares
Sourcing spare parts for vessels in international waters can take months, leading to costly demurrage, idle fleets, and missed commercial deadlines.
03
Large & Obsolete Parts
Many marine components are massive, and casting molds for older vessels often no longer exist. OEMs discontinue parts, leaving operators stranded.
Our Solution
From Physical Warehousing to Digital Inventory
Our Additive Manufacturing solutions bridge the gap between port and vessel, covering two distinct production streams to address every maritime need.
Large-Scale Structural Components

- Propellers & Blades — Bronze or stainless steel, mold-free
- Rudder Systems — Custom heavy-duty steering components
- Deck Equipment — Crane hooks, winches, structural brackets
- Hull Repair Patches — Certified steel plates for emergency use
Complex Functional Parts
Our Laser Powder Bed Fusion (LPBF) technology enables extreme precision for small to medium components with complex internal geometries — impossible to manufacture through traditional casting.
- Heat Exchangers — Optimized lattice structures, 40% lighter
- Valves & Pump Housings — Monolithic, leak-free printing
- Impellers — High-precision complex geometries
- Obsolete Spare Parts — Reverse-engineered legacy components

Manufacturing Process
The Right Technology for Every Part
We deploy the right additive manufacturing technology based on part size, complexity, and performance requirements.
WAAM
Wire Arc Additive Manufacturing
Best For: Massive parts (1m to >5m)
Uses an electric arc to melt metal wire, layer by layer. High deposition rate, low material cost, and ability to produce near-net-shape large structures like propellers and structural beams.
LPBF / SLM
Laser Powder Bed Fusion
Best For: Small to medium, highly complex parts
A high-power laser selectively melts metal powder with extreme precision (±0.05mm). Capable of creating internal cooling channels and lightweight lattice structures impossible with casting.
Traditional Casting vs. Metal 3D Printing
Why leading shipowners and offshore operators are switching to additive manufacturing.
| Feature | Traditional Casting / Forging | Metal 3D Printing (AM) |
|---|---|---|
| Lead Time | Weeks to Months (Mold creation required) | Days (Print directly from CAD file) |
| Tooling Costs | High (Expensive molds and patterns) | Zero (No tooling required) |
| Inventory Strategy | Physical Warehousing (High holding costs) | Digital Inventory (Print on demand) |
| Design Flexibility | Limited by draft angles and machining | Unlimited (Topology optimization allowed) |
| Legacy Parts | Difficult/Impossible if supplier is gone | Easy (3D scan and print) |

Success Stories
Trusted by Maritime Leaders
Hear from shipowners and offshore operators who have transformed their supply chains with Met3DP.
Met3DP delivered a replacement propeller blade in 5 days that would have taken our traditional supplier 14 weeks. The vessel was back in service before the next charter deadline. The quality and corrosion resistance have been outstanding.
Chief Engineer — Global Offshore Fleet Operator
We had a critical heat exchanger failure on an aging FPSO. The OEM no longer existed. Met3DP reverse-engineered the part, optimized the internal channels, and printed a component that outperforms the original by every measure.
Asset Manager — Offshore Energy Company
The transition to digital inventory has fundamentally changed how we approach vessel maintenance. We no longer warehouse thousands of spare parts — we store CAD files and print what we need, where we need it. Met3DP made this vision a reality.

FAQ
Frequently Asked Questions
Are 3D printed marine parts certified?
Yes. We work in accordance with guidelines from major classification societies including DNV, Bureau Veritas (BV), and Lloyd’s Register. Every printed part is tested to ensure it meets the necessary mechanical and chemical properties for marine certification. Full material certificates and traceability documentation are provided.
How does the corrosion resistance compare to casting?
3D printed parts, particularly those made with rapid solidification rates (like SLM/LPBF), often exhibit a finer microstructure than cast parts. This can result in equal or superior corrosion resistance, provided the correct heat treatment and surface finishing are applied. We select and optimize materials specifically for the marine environment.
Can you replace a broken part without a 3D model?
Absolutely. We offer comprehensive reverse engineering services. We can 3D scan your broken or worn-out part, reconstruct the geometry into a full CAD model, and print a brand-new replacement. This is especially valuable for legacy vessels where original OEMs no longer exist or have discontinued the component.
What is the maximum part size you can print?
With our Wire Arc Additive Manufacturing (WAAM) systems, we can produce parts exceeding 5 meters in length. For complex precision parts, our LPBF systems handle components up to approximately 500mm. For larger complex parts, we use a hybrid approach combining WAAM for the bulk structure with CNC machining for precision surfaces.
How quickly can you deliver a part?
Standard parts from existing CAD files can be produced in 3-7 days, depending on size and complexity. For emergency situations, we offer expedited services with priority production scheduling. Reverse engineering adds 2-5 additional business days depending on part complexity. This compares to 8-16 weeks for traditional casting.
